Is a stainless steel water cup with sufficient materials and thick wall must be a good thermos cup?

I saw a comment from a reader at the back of the article introducing lightweight cups, saying that lightweight cups are not good and it is better to use water cups with thick walls and strong materials, which are strong and resistant to falling and can keep warm longer. First of all, thank you friends for reading our article. Secondly, as senior people in the water cup factory, we will compare the lightweight cup with the water cup mentioned by readers. The final result is for everyone to judge. For the convenience of description, we will temporarily refer to the water cup mentioned by readers as “Weight cup”.

In the previous article, the production principle of the “light-measuring cup” and the ultimate use effect were introduced in more detail, so I will repeat it here. “Weight cup” has never been mentioned, because among the countless orders we have received over the years, there is only one project where the customer requested that the wall thickness of the stainless steel water cup be changed to thicker material. We thought that such water cups are rare in the market. Therefore, there is no detailed explanation of the “weight cup”.

“Weight cups” are commonly known as weighted water cups. Usually the wall thickness of water cups is thicker than the back of ordinary water cups. For example, the thickness of stainless steel thermos cups is usually 0.4-0.6 mm, while the wall thickness of “weight cups” is 0.6-1.2 Millimeters, it is not very intuitive to look at it this way. If an ordinary 500 ml stainless steel thermos cup weighs about 240 grams, the weight of the “light measuring cup” is about 160-180 grams, and the weight of the “weight cup” is 380 -About 550 grams, so everyone can have an intuitive comparison.

Most “weight cups” use the tube drawing welding process, and rarely use the stretching process to form. On the one hand, the production cost is too high, and the main reason is that the processing is difficult. The capacity of the finished “weight cup” is generally between 500-750 ml, and there are also a few “weight cups” with a capacity of 1000 ml.

In terms of material comparison, with the same material, the material cost of the “weight cup” is higher than that of the “light cup”, the impact resistance is higher than that of the “light cup”, the weight of the single product is higher than that of the “light cup”, and it is bulky and difficult to carry. High capacity.

In terms of heat preservation, because the “light-measuring cup” adopts the thinning process, the thinner material reduces the heat conduction. Therefore, when comparing the heat preservation properties with the same capacity, the “light-measuring cup” is better than the “weight cup”.

Comparing the use environment, the “weight cup” is more suitable for outdoor use, especially outdoor off-road adventures. The only “weight cup” project that the editor has ever come into contact with was purchased by a well-known foreign military brand. “Weight cups” are not as easy to carry as “light cups” for ordinary people due to their heavy weight.

If you are not a military fan or an avid outdoor cross-country sports enthusiast, it is not recommended to use a “weight cup”. When the weight of a bare water cup exceeds 500 grams and the weight of the water in the cup exceeds 500 grams, it will change whether it is carried or used. become a burden. If you think that thicker materials are stronger and more durable, you are not excluded from choosing a “weight cup”. I can only say that both types of water cups have their own advantages and disadvantages. It cannot be said that heavier water cups are necessarily better.
